test(@angular/build): ensure hash init in i18n inliner tests

The i18n inliner hashes output files which requires the hash utility to be
initialized prior to execution. This adds `initializeHash()` to `beforeAll`
in `i18n-inliner_spec.ts`. Also removes an unused import in `application-code-bundle.ts`.
